Be it known that I, W'ILLARDE. PLAYTER, a citizen of theUnited States of America., residing at Collinsville, lMadison county, State of Illinois, have invented a certain new and useful Bag-Cleaning Apparatus, of which the following is such a full, clear,

and exact description as will enable any one.

skilled in the art to whichA it ppertains to make and use the same, referen e being had to the accompanying drawings, forming part of 'this specification.

My inventionrelates to impuovedi'ineans for removing the fine particlesof material from the fabric of bags which havey been used as containers for flour,- 'ceinent and the like, or which act as strainers-for removing suspended solids from gases, such l as in smelting plants for example.

It is the object of my invention to produce pneumati ally operated bag cleaning means which will be simple and efficient and which will not only dislodge the materialadhering to and collected in the bag fabric, but will also facilitate the removal of the material from the interior-of the b ag and its collection in a'suitable container.

In the accompanying drawings, illustrate onenibodiment of my invention, Figure l is aj'view ,partly in section and partly in elevation,\ showing my .improved bag cleaning apparatus; and Fig. 2 is atiew of a portio of a bag house such as used in, smelting p ants, and .illustrates one collieA niercial application of'thle bag cleaning apparatus of Fig. 1.

The bag cleaning apparatus comprises a flexible tube 2, suitably suspended within the bag to be cleaned, and having one end free to vibrate. I prefer to connect this tube with a suitable` air or fluid reservoir 1 around which they bag 3 may be positioned, being held in place by any convenient means such as a string or wire 5. The lower end of the bag is preferably positioned around a suitable thimble 4 communicating with a material collecting chamber. Air or other suitable fluid, under pressure, is supplied to the reservoir l and, through it, to the flexible tube or beater 2, by means of lthe pipe 6. Thejreactions resulting from air rushing through the tube 2I cause it to vibrate with considerable violence and strike the walls of the bag, thereby dislodging the collected material therefro The current of air from the end ofthetube passes downward which speieatign of Letters raient.

carrying the dislodged vmaterial with it. When the supply of air is cut olf, the air under pressure 'in1 the reservoir 1 supplies a relatively slow and v gentle current of air to the interior -of the bag for a short time after the tube 2 has ceased to vibrate, with the result that practically all of the dis-z lodged material is carried out of the in- 'terior of the bag. `While air is flowing .es downwardly fromthe tube 2, 1t, of course,

tends to create a vacuum in the upper part l i of the bag and therefore, to draw air through the upper part of the walls of the bag; and thus downward currents of air are established throughout the whole inbein communicationwith a single pipe 6 taneously, the' dislodged material flowing into the compartment 8 beneath the bag house floor. After the cleaning of the bags,

,frnace gases are vaulmitted to them from a conduit 9 through the 'opening controlled controlled by the valve 7 and cleaned simul-v the damper l10 and, when the wallsof the .I

'ft-pig are again filled with material collected 'i2-.rom the furnace gases, the damper 10 is closed and the cleaning operation just described repeated. v

The collecting chambers used with my bag cleaning apparatus should be of sulii' cient capacity and have suflicient opening for the outlet of air in order that there may be no strong currents ef'air though the col lecting chamber while the bag cleaning apparatus is operating.'

Having fully described my invention,

what I claim as new and desire to Vsecure by Letters Patent of the United States is:

l. Bag cleaning apparatus comprising a flexible tube having a free end adapted to be positioned within a bag to be cleaned, and means for passing air or other fluid through the tube to cause the free end to vibrate and strike the bag. 2. In a bag cleaning apparatus, the comhina-tion of a flexible tube having a free end and supported in operative relation with-a m 1,:1. iepe/ie heg' fno he ceme, and means for foaming pair oi other Huid through seid tube to cause the free-end thereof t stiike the beg.

3. In a bag cleaning apparatus, the combination of a iexible tube having a free'end 'and Suppote iu operative relation with a bag to'be cleaned, means for forcing air or other Huid through-seid tube. to cause the free end 'thereof to strike the hug, e valve for controlling the Supply of air to the tube, and an air ieservoir between said Valve and the tube.
